FAQ:
Q1: Why choose 321 over 304 stainless steel?
A: 321 contains titanium, offering better high-temperature and intergranular corrosion resistance.
Q2: What is bright annealing?
A: It's a heat treatment in a controlled atmosphere that enhances surface smoothness and corrosion resistance.
Q3: Can 321 stainless pipes be welded easily?
A: Yes, they have excellent weldability with minimal risk of carbide formation.
